[Koha-patches] [PATCH] Followup to Bug 4305: multiple ISBNS in biblioitems.isbn breaks patron

[Ian Walls]

This patch adds a scrub for ' | ' when the ISBN comes from the
biblioitems table, in the event that Koha has attempted to store
multiple ISBNs in the field.  The ISBN presented to Business::ISBN will
now be something it can handle.
